Young Justice is an upcoming animated series. It seems that after the premiere episode, various depictions of them have been popping up. But this one is reassembles their animated counterparts the most.

I hate these kind of images. It's like the artist was really lazy and didn't finish them. The brush strokes are so obvious it ruins the mood.

That's the point, it's conveying the image in the style of proper painting: convey the point across with colour. It requires the most skill to be successful at it.

Since you do 3d you should know that's what environment concept art will nearly always look like. They're not supposed to fully flesh it out. They're supposed to create mood and stylistic direction and the images clearly succeeded at that.

There's a really awesome Japanese photographer that takes pictures of female models and such...
The thing is, he basically asks them "How do you want to die?.." They tell him, and then he takes pictures of them like that... But I cant remember the name, can anybody help me? :)

This is the crazy bastard.

Famous for such pictures as;

I dont really have any favorites because they're all so good in their own way, but I'll pick out a few good ones.

Then there is H.R. Giger
If you dont know him, you'll recognize his work as he created Alien and a few other things.
